Omni-Man!
"As a Viltrumite, it was my duty to ready the planet I was assigned to for the Empire and make it better. And when I got to Earth, I slowly began to gain the trust of it's fragile populace. Then I began my conquest once my son, Mark, came into the picture.
So I began by murdering the Guardians of the Globe and then I kicked the crap out of my invulnerable son when tried to stop me.
I lectured him on what was more valuable when those you love eventually die, he told me that he would have me.
I...
I... didn't know how to respond to that.
So, I left the planet, when was uncommon for my race as we were known for our relentlessness and refusal to surrender.
Of course, I didn't really surrender l just... clear my head a bit.
Once I was far enough away from the solar system, that was when I found myself transported to an entirely different universe by this Brainiac guy.
When he came face to face with me, he has studied my race for a while as he told me that it was kind of like these Kyptonian people he slaughtered except for two. Superman and Supergirl and he wanted to use my power for universal conquest.
Like hell I was going to help him take over this universe himself. What was he thinking?
Think Brainiac, think!
That was the only thing I thought of as I brutally killed him. Speaking of which, taking Brainiac out then drew the attention of what were apparently this universe's Guardians of the Globe who were apparently at war with each other.
Superman wanted me to join his Regime for killing Brainiac while this Batman guy wanted me detained for killing him.
It was almost like my fight with my son in a way.
I refused to join either of them as I just wanted to go back to my universe, with Brainiac's ship as the ultimate planet conquering weapons for the Viltrumite empire.
When they refused to let me leave either way, with Brainiac's ship or not, I came to blows with all of them.
And quite the battle it was for someone who wasn't holding back.
With everyone else dead, only Superman and I were the only ones left who still alive.
The last of the Kyptonians and one of the strongest of the Viltrumites.
By the end of it, our battle left many people dead or with PTSD and Superman dead at my feet.
With no powerhouses left to stop me, all that was left was to take out the small fries. Though they were quite resilient, they were no match for my might.
Maybe it wasn't my Earth, but I completed my mission regardless of the opposition.
With Brainiac's ship, I conquered planet after planet... Until I got to Apokolypse, Darkseid's home planet.
All I could say to him was...
BRING IT ON!"
